ios - Using NSUserDefaults to share data to watchkit -


i trying use nsuserdefaults share data watchkit files. trying have when button function executed watchlabel.settext data array. array , function selects data created in ios application. (unfortunately many resources come across in objective-c or extremely vague.)

  • i have set app groups both ios , watchkit

  • in ios swift file trying share array(arraybook) , function(.randomdata) use watchkit controller. ps: have no compiler errors. 

    let shareddefaults = nsuserdefaults(suitename: "group.applewatchtest")  shareddefaults?.arrayforkey(arraybook.randomdata())  shareddefaults?.synchronize()

  • watchkit controller; unsure correct syntax fetching data , setting label random string array. - within uibutton func. 

    let shareddefaults = nsuserdefaults(suitename: "group.applewatchtest")  let sharedarray = shareddefaults?.arrayforkey("shared")  watchlabel.settext(arraybook.randomdata())

where going wrong when fetching data set label data array stored in ios application. 

shareddefaults?.arrayforkey(arraybook.randomdata())

this line of code not doing anything. you're reading array defaults, using key of whatever arraybook.randomdata() returns, , doing nothing it.

i assume want like

shareddefaults?.setobject(arraybook, forkey:"shared")

which write array defaults. out in watch (which looks fine) , random value using randomdata().
